Recipe for cheesy Au Gratin Potatoes

Potatoes. If there was a popularity contest for vegetables, I’m pretty sure potatoes would win. Is there anyone who doesn’t like them? Even the pickiest eaters I’ve ever heard of (that thankfully don’t reside at my house), will eat potatoes. They are the ultimate comfort food.
Au Gratin Potatoes- Layers of tender potatoes surrounded with creamy cheddar cheese sauce.I love potatoes in just about any form, but these au gratin potatoes top my list. That crunchy cheesy part at the top just sucks me in. I could totally scrape the top off and eat it all by myself. But I don’t. That wouldn’t be nice.

Of course, underneath that crunchy top, there is the creamy, ooey gooey cheese filled goodness. So much yummy-ness all in one pan!
Au Gratin Potatoes are a delicious side dish any time of year!This time around, I used potatoes that were ginormous, so it threw off the sauce/potato ratio. Still delicious, but not quite as saucy. So if you like that sauce in the middle, make sure your potatoes are just medium sized.

Yield: 6-8 servings

  1. Nothing more comforting than au gratin potatoes! These look delicious!

  2. This post made me giggle to myself a little. My husband cracks me up when it comes to certain things. If I tell him I am making au gratin potatoes, he will turn up his nose and not eat them. Same thing with potato pancakes. So, I serve him cheesy potatoes and latkes and he likes them! It’s all in the branding 😉 These look delicious and I am sure he would love them as “cheesy potatoes,” as long as nobody blows my cover.

    • Haha, that is hilarious Carlee! The things we have to do to get people to eat sometimes. . . . 🙂
